Abstract (en)

[origin: WO03028312A1] The invention relates to a method for establishing a connection and short-range radio transceiver unit for carrying out said method, whereby an inialisation of a first transmission power value (E2) occurs and a search for a second short-range transceiver unit in a radio coverage area (E3, E4) as determined by the first transmission power value. On finding a second short-range radio transceiver unit, storage of the characteristic information of the second short-range radio transceiver unit along with the first transmission power value is carried out (E4, E5). A comparison of the first transmission power value with a second transmission power value is then carried out (E6), whereby if equality is found the search is ended and where inequality is found the search is repeated with a modified first transmission power value (E8, E3, E4).
